Potential Measles outbreak scare in California after over 100 children exposed at Sacramento program, all you need to know about the disease and symptoms

Health officials in Sacramento County are warning of a potential measles outbreak after more than 100 children were possibly exposed to the highly contagious virus at an educational enrichment program attended by an unvaccinated child who was infectious at the time.

Authorities say up to 130 children may have come into contact with the virus, prompting urgent monitoring and public health alerts.

According to NewYork post website, the enrichment program has temporarily closed its facility after public health officials warned that up to 130 children may have been exposed to the virus.


Dr. Erica Pan, CDPH Director and State Public Health Officer, said, “Measles, one of the most contagious infections, can lead to severe life-long consequences, including permanent brain damage and can also be fatal, especially for children.”

Health officials said the Measles, Mumps, and Rubella vaccine is safe and provides long-lasting protection, helping safeguard families and children who are not yet fully vaccinated.

According to CDC website, as of March 5, 2026, the United States had reported 1,281 confirmed measles cases nationwide.

What is Measles?

Measles is a highly contagious viral disease caused by the measles virus and spreads easily through respiratory droplets when an infected person coughs or sneezes. It typically begins with symptoms such as high fever, cough, runny nose, and red, watery eyes, followed by a distinctive red rash that spreads across the body.

The disease can lead to serious complications, especially in young children, including pneumonia, brain inflammation, and in severe cases, death.

Measles is preventable through the widely used Measles, Mumps, and Rubella vaccine, which provides strong and long-lasting protection against the virus.

According to New York Post website, at least six measles cases have been confirmed since late February in Sacramento County and neighboring Placer County.

Concern also spread to Kaiser Permanente Roseville Medical Center after one of the infected children was treated there on the morning of March 2, prompting the hospital to trace and notify patients and staff who were present at the time.
